I have been scouring the web to see if the Galaxy Nexus muting problem has been fixed. I have been waiting months for 4.04 assuming the issue would be resolved, but the problem still exists (When I talked to a worker in store they assured me the fix would be coming in 4.04).

Some people say that Wired Headset Routing Fix works and some say it doesn't.
There is also a claim that Verizon is slowly fixing the problem and that the issue is slowly going away.
Those of you who have the muting issue has it become less frequent?
I only updated the Radio, but it shouldn't matter since 4.0.4 has been out for a while and been used in ROMs that still had the bug?
It seems to have gotten a little bit better for me, I was able to make 2 calls in a row without having the problem... I am trying to decide whether to wait a little longer or switch to the Razr Max, I really like this phone... err... device and I don't want to give up future updates but I am tired of having to use my wife's phone for making calls.
Edit: For those not in the know, the muting bug happens in the middle of a call, where suddenly the people on the other end cannot hear you anymore. It cannot be fixed by toggling the mute button on the phone, and getting a replacement phone will not help as the issue is somehow tied to the account (Assumption based on my reading).
